Pump Curves
Pump Curves
(OP)
Can anyone tell me if there are curves that show the starting of a pump?
I would like to know how long it is going to take for a certian pump to start based on being connected to a motor, so far the manufacturer has just given me motor information which has nothing to do with how long it is going to take for this pump to get up to running speed and I don't know if I should keep bugging them for this information if it does not exist.
Thanks

It will be an induction motor,
The pump in question is a vacuum pump so I would assume it's considered starting at run-out.
I am currently contacting the sales rep to see if he can get me a speed-torque curve.
May have more questions if I ever get this curve.

Using the online gospel, AKA Google Search, on "76.4% of all statistics are made up" proves this stat is spot on =)

RE: Pump Curves
What motor size is this. Is it a NEMA standard frame size?
